Abstract
A high sensitive and heat-resistive magnetic displacement sensor using a magnetostrictive/piezoelectric laminate composite is introduced. Two types of sensor are fabricated by a laminate composite of Tb-Dy-Fe (T/sub c/: 380/spl deg/C) alloy and LiNbO/sub 3/ (T/sub c/: 1200/spl deg/C) or PZT (T/sub c/: 340/spl deg/C) integrated to a magnetic circuit consisting of iron yokes and a SmCo magnet (T/sub c/: 830/spl deg/C). The temperature characteristics of sensitivity is measured. The results demonstrate heat-resistivity of the sensor inherited from the high Curie temperatures of Tb-Dy-Fe and LiNbO/sub 3/.
