The magnetic properties of alkali-metal peroxychromate K$_2$NaCrO$_8$ are governed by the $S = 1/2$ pentavalent chromium cation, Cr$^{5+}$. Specific heat, magnetocalorimetry, ac magnetic susceptibility, torque magnetometry, and inelastic neutron scat

Entrapment of magnetic micro-crystals for on-chip electron spin resonance studies

Autor: Groll, N., Bertaina, S., Pati, M., Dalal, N. S., Chiorescu, I.

Publikováno v: J. Appl. Phys., 106 (4), 046106 (2009)

On-chip Electron Spin Resonance (ESR) of magnetic molecules requires the ability to precisely position nanosized samples in antinodes of the electro-magnetic field for maximal magnetic interaction. A method is developed to entrap micro-crystals conta

Electron Spin Relaxation and 39K Pulsed ENDOR Studies on Cr5+ doped K3NbO8 at 9.7 and 240 GHz

Autor: Nellutla, S., Morley, G. W., Pati, M., Dalal, N. S., van Tol, J.

Publikováno v: Phys. Rev. B 78, 054426 (2008)

Cr^5+ doped K_3NbO_8, considered to be useful as a electron spin qubit, has been investigated by pulsed X-band (~9.7 GHz) and 240 GHz electron paramagnetic resonance and electron nuclear double resonance (ENDOR). Comparison of the low temperature ele

Report

Coherent manipulation of electron spins up to ambient temperatures in Cr$^{5+}$(S=1/2) doped K$_3$NbO$_8$

Autor: Nellutla, S., Choi, K. -Y., Pati, M., van Tol, J., Chiorescu, I., Dalal, N. S.

Publikováno v: Phys. Rev. Lett. 99, 137601 (2007)

We report coherent spin manipulation on Cr$^{5+}$ (\emph{S} = 1/2, \emph{I} = 0) doped K$_3$NbO$_8$, which constitutes a dilute two-level model relevant for use as a spin qubit. Rabi oscillations are observed for the first time in a spin system based
