Biaxial magnetic field setup for angular magnetic measurements of thin films and spintronic nanodevices

摘要

The biaxial magnetic-field setup for angular magnetic measurements of thinfilm and spintronic devices is designed and presented. The setup allows forapplication of the in-plane magnetic field using a quadrupole electromagnet,controlled by power supply units and integrated with an electromagnet biaxialmagnetic field sensor. In addition, the probe station is equipped with amicrowave circuitry, which enables angle-resolved spin torque oscillationmeasurements. The angular dependencies of magnetoresistance and spin diodeeffect in a giant magnetoresistance strip are shown as an operationalverification of the experimental setup. We adapted an analytical macrospinmodel to reproduce both the resistance and spin-diode angular dependencymeasurements.
