In-plane magnetic anisotropy of the Sr4Ru3O10 nanosheet probed by planar Hall effect

The planar Hall effect (PHE) in a ruthenate Sr4Ru3O10 nanosheet as a function of the magnetic field direction and temperature has been investigated. From the magnetic reversal induced PHE signal, we find that the [ 1 ¯ 10] direction is the in-plane ferromagnetic easy-axis and the [110] direction is...

Summary:The planar Hall effect (PHE) in a ruthenate Sr4Ru3O10 nanosheet as a function of the magnetic field direction and temperature has been investigated. From the magnetic reversal induced PHE signal, we find that the [ 1 ¯ 10] direction is the in-plane ferromagnetic easy-axis and the [110] direction is a metastable magnetic axis of the Sr4Ru3O10 nanosheet. This in-plane magnetic anisotropy can lead to a large, measurable, and field direction sensitive resistance switching when an in-plane magnetic field is swept, suggesting that Sr4Ru3O10 may have potential applications in spintronic and magnetic sensor devices.
