The magnetic ground state of an electron-doped cuprate superconductor Pr$_{1-x}$LaCe$_x$CuO$_{4+\alpha-\delta}$ ($x=0.11, \alpha\simeq0.04$) has been studied by means of muon spin rotation/relaxation...
Quasiparticle Excitations outside the Vortex Cores in MgB$_2$ Probed by Muon Spin Rotation (2002)
Ohishi, Kazuki, Muranaka, Takahiro, Akimitsu, Jun, Koda, Akihiro, Higemoto, Wataru, Kadono, Ryosuke
The magnetic penetration depth $\lambda$ in the mixed state of MgB$_2$ has been determined microscopically from the field distribution around magnetic vortices probed by muon spin rotation. Both the...
