Spin excitations of the correlated semiconductor FeSi probed by THz radiation
By direct measurements of the complex optical conductivity of
FeSi we have discovered a broad absorption peak centered at frequency
that develops at temperatures below 20 K.
This feature is caused by spin-polaronic states formed in the middle of the gap
in the electronic density of states. We observe the spin excitations between
the electronic levels split by the exchange field of . Spin
fluctuations are identified as the main factor determining the formation of the
spin polarons and the rich magnetic phase diagram of FeSi.Comment: 5 pages, 4 figure
Reduction of naughty behavior of preschool children by means of play
Upbringing of a naughty child is one of the most important topics in early childhood education. Lots of parents and almost all the kindergartenТs teachers often deal with misbehavior of youngsters. One of the effective means of reducing the symptoms of preschool childrenТs misbehavior is play
