摘要：
The temperature dependence of exchange biased planar Hall effect sensors is investigated between T = -10 and 70 degrees C. it is shown that a single domain model describes the system well and that the temperature coefficient of the low-field sensitivity at T = 25 degrees C is 0.32%/degrees C. A procedure for temperature correction by use of a reference sensor is demonstrated. Consequences for magnetic biosensing are exemplified with calculations on M-280 Dynabeads (R).
