Abstract
Provided are a magneto-optical material capable of enhancing the tunable range of magneto-optical properties such as the Faraday rotation angle, and a method for producing the same. The temperature of a substrateis controlled to a first temperature within the range of 300 to 800 [° C.], and the atmospheric pressure of the substrateis controlled to 1.0×10[Pa] or less (first step). Using a composite target or plurality of individual targets of a TCO material exhibiting ENZ properties in the infrared wavelength region, together with a magnetic metal, a magneto-optical materialis deposited on the substratewhile the temperature of the substrateis controlled to a second temperature within the range of 300 to 800 [° C.], and the atmospheric pressure of the substrateis controlled to the range of 0.1 to 10 [Pa] (second step).
