Methods and devices for three-dimensional navigation of magnetic nanoparticles are provided. A method can comprise introducing high-anisotropy magnetic nanoparticles to a mammal and directing the high-anisotropy magnetic nanoparticles towards a target region of the mammal. Direction control is achieved by subjecting the high-anisotropy magnetic nanoparticles to an alternating signal comprising a uniform magnetic field pulse having a strength greater than a coercivity of the high-anisotropy magnetic nanoparticles and a magnetic gradient pulse having a highest strength that is less than the coercivity of the high-anisotropy magnetic nanoparticles and a location of a lowest strength at the target region of the mammal, and the direction of the uniform magnetic field pulse being in an opposite direction of the magnetic gradient pulse.

3D navigation of nanoparticles via induction of metastable diamagnetic response

A compact magnetic-based battery device that offers energy, a large number of cycles, a long storage time, and a short charging time is provided. The rechargeable battery device can include a first magnetic layer, a second magnetic layer, a dielectric layer disposed between the first magnetic layer and the second magnetic layer, and a plurality of high anisotropic magnetic nanoparticles embedded into the dielectric layer.

Rechargeable battery device

Systems for screening and health monitoring of materials are provided. The system can include a material embedded with magneto-electric nanoparticles (MENs), a laser configured to direct incident laser light waves at a target area of the material, an optical filter disposed between the laser and the material, and an analyzer configured to detect the laser light reflected from the material.

Rapid and wireless screening and health monitoring of materials and structures

A spintronic device can include a bottom contact layer, a bottom magnetic layer disposed on the bottom contact layer, a nanoparticle layer disposed on the bottom magnetic layer, a top magnetic layer disposed on the nanoparticle layer, and a top contact layer disposed on the top magnetic layer. The spintronic device can include a bottom insulation layer disposed between the bottom magnetic layer and the nanoparticle layer, and a top insulation layer disposed between the nanoparticle layer and the top magnetic layer.

Nanoparticle based computing architecture

Instantly rechargeable battery device

Disclosed herein are methods of delivering drugs to a subject in a controlled release fashion by administering a magneto-electric nanoparticle having ionic bonds to a drug then applying a magnetic field to weaken the ionic bonds and release the drug.

On-demand drug release using magneto-electric nanoparticles

Magneto-electric nanoparticles in a subject interact with an external magnetic field to cause stimulation of neural networks in the subject. Electric signals in the neural network are coupled to magnetic dipoles induced in the nanoparticles to cause changes in electric pulse sequences of the subject's brain.

Method for non-invasive brain stimulation

An electronic memory and/or recording device includes a three dimensional magnetic medium. Three dimensional magnetic medium includes a plurality of magnetic sublayers, each of the magnetic sublayers being separated from one other by non-magnetic interlayers.

Three dimensional magnetic memory and/or recording device

A write pole for a magnetic recording head, such as a perpendicular magnetic recording head, includes a first magnetic layer comprising a material having a first saturation magnetic moment and a second magnetic layer adjacent the first magnetic layer wherein the second magnetic layer comprises a material having a second saturation magnetic moment that is greater than the first saturation magnetic moment. The write pole also comprises a non-magnetic layer between a portion of the first magnetic layer and the second magnetic layer. The non-magnetic layer may be formed between the first magnetic layer and the second magnetic layer adjacent an air-bearing surface of the recording head. A disc drive storage system having a recording head with means for reducing skew sensitivity of the recording head is also disclosed.

Low moment-high moment write pole with non-magnetic layer for establishing a magnetic path discontinuity between layers of the write pole

A perpendicular magnetic recording system is provided which eliminates unwanted side writing to adjacent recording tracks due to the skew angle effect. The system includes a perpendicular magnetic recording head with a write pole that is used to sequentially write to adjacent tracks of a magnetic recording disk. In one embodiment, the write pole is aligned at a compensation angle with respect to the recording tracks which remains greater than zero as the recording head travels in an arc across the disk. When the recording head moves radially inwardly or outwardly across the tracks of the disk, the compensation angle remains greater than zero. Any side writing by the write pole to adjacent tracks is eliminated as the write pole sequentially writes to the next adjacent track. By eliminating the skew angle effect, smaller spacings may be provided between adjacent tracks, thereby increasing data storage densities.
