Abstract: A composite magnetic ring has a plurality of permanent magnets arranged in a ring shape at a prescribed spacing, and low-temperature Curie point magnetic substances sandwiched between each adjacent permanent magnets. An energy converter, that converts exhaust heat energy or sunlight heat energy to mechanical or electrical energy by alteration of the magnetic permeability of low-temperature Curie point magnetic substances in the composite magnetic ring near their Curie point, includes a composite magnetic ring and a rotor situated inside the composite magnetic ring and having a plurality of magnetic poles, at least one of the low-temperature Curie point magnetic substances in the composite magnetic ring being heated to a temperature near its Curie point and a magnetic field being generated in the vicinity of the heated low-temperature Curie point magnetic substance, to rotate the rotor.

Abstract: A high frequency magnetic thin film characterized by comprising a first layer made of a T-L composition (here, T is Fe or FeCo, and L is one or more of C, B, and N) and a second layer comprising a Co-based amorphous alloy arranged on either of the surfaces of the first layer. The high frequency magnetic thin film is a multilayer film of a plurality of the first layers and a plurality of the second layers or desirably is a multilayer film of alternately laminated first and second layers. The high frequency magnetic thin film of the present invention exhibits the properties such that the real part (??) of the complex permeability is 400 or more at 1 GHz, a quality factor Q (Q=??/??) is 4 or more, and a saturation magnetization is 14 kG (1.4 T) or more.
