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…

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…
