New publication on artificial spin ice phase transitions!
We experimentally examine the ground state transition from antiferromagnetic to ferromagnetic order in a artificial spin ice triggered by rotation of nanomagnets.
The as-grown magnetic configurations well agree with Monte Carlo simulations and ascribe a unique effective temperature independent of the rotation angle. Deviations from the theoretical ground state and behavior at transition are therefore well explained.
