Effect of doping on irreversible Campbell length in MgB$_2$ single crystals (2008)
Martin, C., Vannette, M. D., Gordon, R. T., Prozorov, R., Karpinski, J., Zhigadlo, N. D.
We have measured small-amplitude rf penetration depth $\lambda(H,T)$ in pure and C, Li and (Li+C) doped single crystals of MgB$_2$. The effect of doping on the critical temperature T$_c$ and on the...
Martin, C., Gordon, R. T., Tanatar, M. A., Vannette, M. D., Tillman, M. E., Mun, E. D., ...
In- and out-of- plane magnetic penetration depth was studied in single crystals of NdFeAsO$_{0.9}$F$_{0.1}$. The low temperature behavior of the in-plane London penetration depth, $\lambda_{ab} (T)$,...
Field-dependent AC susceptibility of itinerant ferromagnets (2008)
Whereas dc measurements of magnetic susceptibility, $\chi$, fail to distinguish between local and weak itinerant ferromagnets, radio-frequency (rf) measurements of $\chi$ in the ferromagnetic state...
Prozorov, R., Vannette, M. D., Law, S. A., Bud'ko, S. L., Canfield, P. C.
Tunnel-diode resonator technique was used to study crystals of ferromagnetic re-entrant superconductor, ErRh$_{4}$B$_{4}$. At the boundary between ferromagnetism (FM) and superconductivity (SC),...
^{7}Li NMR Study of Heavy Fermion LiV2O4 Containing Magnetic Defects (2008)
Zong, X., Das, S., Borsa, F., Vannette, M. D., Prozorov, R., Schmalian, J., ...
We present a systematic study of the variations of the ^{7}Li NMR properties versus magnetic defect concentration up to 0.83 mol% within the spinel structure of polycrystalline powder samples and a...
Gordon, R., Vannette, M. D., Martin, C., Nakajima, Y., Tamegai, T., Prozorov, R.
Single crystal of Lu$_2$Fe$_3$Si$_5$ was studied with the tunnel-diode resonator technique in Meissner and mixed states. Temperature dependence of the superfluid density provides strong evidence for...
s-Wave superconductivity in non-centrosymmetric Re_3W probed by magnetic penetration depth (2007)

We report measurements of the temperature dependence of the magnetic penetration depth \lambda(T) in non-centrosymmetric superconductor Re_3W. We employed two experimental techniques: extraction of...
Vannette, M. D., Safa-Sefat, A., Jia, S., Law, S. A., Lapertot, G., Bud'ko, S. L., ...
Dynamic magnetic susceptibility, $\chi$, was studied in several intermetallic materials exhibiting ferromagnetic, antiferromagnetic and metamagnetic transitions. Precise measurements by using a 14...
Radio-frequency magnetic response of vortex lattices undergoing structural transformations (2007)
Prozorov, R., Kogan, V. G., Vannette, M D., Bud'ko, S. L., Canfield, P. C.
We report a clear anomaly in the rf response of a tunnel-diode resonator measured in borocarbide crystals in dc fields along the $c-$axis. We associate the anomaly in the dynamic magnetic...
Superconducting and normal state properties of the layered boride OsB2 (2006)
Singh, Yogesh, Niazi, A., Vannette, M. D., Prozorov, R., Johnston, D. C.
OsB_2 crystallizes in an orthorhombic structure (Pmmn) which contains alternate boron and osmium layers stacked along the c-axis. The boron layers consist of puckered hexagons as opposed to the flat...
