Abstract

PURPOSE: To suppress the temperature rise of a chip by providing plates made of a boron nitride or silicon single crystal in a space surrounded with an internal coil, magnetic adjusting plates and permanent magnets and by interposing grease, containing boron-nitride powder, between the provided plates and the contact surface of the internal coil, magnetic adjusting plates and permanent magnets.
CONSTITUTION: In the area surrounded with internal coil 2, magnetic adjusting plates 5 and permanent magnets 4, boron-nitride(BN)-formed plates or silicon single-crystal plate 7 and 7' of high electric resistance and excellent thermal conductivity are provided. Between those conductive layers 7 and 7', and internal coil 3, magnetic adjusting plates 5 and permanent magnets 4, conductive grease containing a volume of BN powder is interposed so as to improve the thermal conductivity. Consequently, the temperature rise of the magnetic bubble chip can be suppressed.
