The 55Mn NMR has been measured in LaxSr1 - xMnO3 for x = 0.2 and 0.3 as a function of temperature, in zero field and in field. The samples had a room temperature resistivity of 10-4 ohm-cm, and the magnetizarion showed a sharp FM transition 312 K. Th

In contrast with the simultaneous structural and magnetic first order phase transition T0 previously reported, our detailed investigation on an underdoped Ba(0.84)K(0.16)Fe2As2 single crystal unambiguously revealed that the transitions are not concom

The responses to the magnetic field ( H ) of the superconductivity and the pseudogap in the underdoped high- T c cuprate YBa 2 Cu 4 O 8 ( T c =74 K ) are reported up to 23.2 T based on NMR measurements. For temperatures T⩽15 K , the H - and T -vari

The responses to the magnetic field (H) of the superconductivity and the pseudogap in the underdoped high- T c cuprate YBa 2 Cu 4 O 8(Tc=74 K) are reported up to 23.2 T based on NMR measurements. Even though H=23.2 T reduces Tc by 19 K, no effect is

We report measurements of 63,65 Cu nuclear quadrupole resonance (NQR) at ambient temperatures to indirectly probe Ba-site occupation of Pr atoms in doped Y 1-x Pr x Ba 2 Cu 3 O 7-δ (0≤x≤1.0). Preliminary results show anomalous peaks in the spect

Niobium films (120 nm thick) deposited by electron-beam evaporation were implanted near 5 K with 100 keV N2 ions to maximum fluences of 4 to 7 × 1017 N/cm2. STEM diffraction patterns showed a structural phase transformation from the initial Nb latti

Highly spin polarized (SP) and half-metallic ferromagnetic systems are of considerable current interest and of potential importance for spintronic applications. Recent work has demonstrated that Co1-xFexS2 is a highly polarized ferromagnet (FM) where

The detailed understanding of electron‐nucleus interactions and spin manipulation processes in semiconductors is of crucial importance in the development of new technology based on spin degrees of freedom. We have shown that dynamic polarization of
