Controlled creation and annihilation of stringless robust emergent magnetic monopoles in artificial spin ice
N. Keswani, R. Lopes, Y. Nakajima +6
Magnetic analogue of an isolated free electric charge, i.e., a magnet with a single north or south pole, is a long sought-after particle which remains elusive so far. In magnetical…
Accessing low-energy magnetic microstates in symmetry-broken isolated square artificial spin ice vertices with magnetic field
Neeti Keswani, Ranveer Singh, Yoshikata Nakajima +3
In artificial spin ice systems, an interplay of defects and dipolar interactions is expected to play important roles in stabilizing different collective magnetic states. In this wo…
Magnetization reversal of dipolar coupled nanomagnets studied by two-dimensional electron gas based micro-Hall magnetometry
N. Keswani, Y. Nakajima, N. Chauhan +6
We report here the results of two-dimensional electron gas based micro-Hall magnetometry measurements and micromagnetic simulations of dipolar coupled nanomagnets of Ni80Fe20 arran…
On the micromagnetic behavior of dipolar-coupled nanomagnets in defective square artificial spin ice systems
Neeti Keswani, Pintu Das
We report here the results of micromagnetic simulations of square artificial spin ice (ASI) systems with defects. The defects are introduced by misaligning of a nanomagnet at the v…
