A Spectral Analysis of Laser Induced Fluorescence of Iodine
S. B. Bayram, M. V. Freamat
When optically excited, iodine absorbs in the 490- to 650-nm visible region of the spectrum and, after radiative relaxation, it displays an emission spectrum of discrete vibrationa…
Rotational spectra of N: An advanced undergraduate laboratory in atomic and molecular spectroscopy
S. B. Bayram, P. T. Arndt, M. V. Freamat
We describe an inexpensive instructional experiment that demonstrates the rotational energy levels of diatomic nitrogen, using the emission band spectrum of molecular nitrogen ioni…
Dynamics of the Electro-Optic response of Blue Bronze
L. Ladino, J. W. Brill, M. Freamat +2
We have studied the charge density wave (CDW) repolarization dynamics in blue bronze by applying square-wave voltages of different frequencies to the sample and measuring the chang…
Thermal and Magnetic Properties of the Spin-Chain Material, Pr3RuO7
M. Freamat, X. N. Lin, V. Durairaj +3
We present measurements of the magnetic moment and specific heat of single crystals of the spin-chain insulator, Pr3RuO7. The susceptibility indicates that three-dimensional antife…
Andreev bound states in normal and ferromagnet/high-Tc superconducting tunnel junctions
Mario Freamat, K. -W. Ng
Ag/BSCCO and Fe/Ag/BSCCO planar tunnel junctions were constructed in order to study experimentally the effect of an exchange potential on the spin polarized current transported thr…
Order parameter oscillations in Fe/Ag/Bi2Sr2CaCu2O{8+delta} tunnel junctions
Mario Freamat, K. -W. Ng
We have performed temperature dependent tunneling conductance spectroscopy on Fe/Ag/Bi2Sr2CaCu2O8 (BSCCO) planar junctions. The multilayered Fe counterelectrode was designed to pro…
Temperature and Field Dependence of the Energy Gap of MgB2/Pb planar junction
Mohamed H. Badr, Mario Freamat, Yuri Sushko +1
We have constructed MgB2/Pb planar junctions for both temperature and field dependence studies. Our results show that the small gap is a true bulk property of MgB2 superconductor,…
