Title: Biaxial magnetic field setup for angular magnetic measurements of thin films and spintronic nanodevices,
Abstract: The biaxial magnetic-field setup for angular magnetic measurements of thin
film and spintronic devices is designed and presented. The setup allows for
application of the in-plane magnetic field using a quadrupole electromagnet,
controlled by power supply units and integrated with an electromagnet biaxial
magnetic field sensor. In addition, the probe station is equipped with a
microwave circuitry, which enables angle-resolved spin torque oscillation
measurements. The angular dependencies of magnetoresistance and spin diode
effect in a giant magnetoresistance strip are shown as an operational
verification of the experimental setup. We adapted an analytical macrospin
model to reproduce both the resistance and spin-diode angular dependency
measurements.
