Magnetizem in superprevodnost

Študenti bodo spoznali magnetizem in superprevodnost. To je kolektivni fenomen, ki ga ni mogoče opisati z modelom neodvisnega elektrona.

V okviru predmeta bodo spoznali eksperimentalna dejstva in teoretične opise magnetizma in superprevodnosti, potek raziskav v magnetizmu in magnetne materiale povezane z elektroniko, ki temelji na spinskem stanju -
»spintroniko«.

Približno 2/3 vsebine vključuje magnetizem in 1/3 superprevodnosti.

Nekonvencionalni superprevodniki

Študenti bodo pridobili znanje o fiziki magnetov in superprevodnikov. Pridobili bodo znanje od fiziki koreliranih elektronov.
