High energy spin excitation in superconducting Rb0.8Fe1.68Se2
Superconductivity (SC) in unconventional superconductors is believed to be related to magnetism. However, in AyFe1.6+xSe2 (A = K, Rb, Cs) system discovered in late 2010, the SC... -
Spin excitations in overdoped BaFe1.2Ru0.8As2 (Tc=10 K)
Overdoped BaFe1.2Ru0.8As2 is an ideal system for comparison study between band structure calculation and spin excitation spectrum, because the electron correlation is expected... -
Low Energy Dispersion of a Stripe-Ordered, Hole-Doped Antiferromagnet
Our previous studies of the hole-doped antiferromagnet La1.75Sr0.25CoO4 have shown the distinctive "Hour-Glass" dispersion attributed to magnetic and charge ordered stripes.... -
Magnon diffusion in the spin Seebeck material magnetite
The spin Seebeck effect is a newly discovered phenomenon that if harnessed, could result in a significant improvement of the efficiency of thermoelectric energy generators. SSE... -
Spin excitation in magnetic Weyl semimetal HgCr2Se4
Topological materials get extensive attention in last three decades. HgCr2Se4 is one of those materials being a Weyl semimetal which is induced by time-reversal symmetry... -
Magnetic Fluctuations in BaCo2As2
ACo2As2 (A=Ba, Sr, Ca) are end members of Co doped Ba-122 family. Understanding the magnetic behavior of these end members can help us to understand the magnetic properties of...
