We report direction dependent magnetization measurements in LSCO single crystals. The crystals were grown using traveling solvent floating zone method and where cut into rectangular needle-like shapes with the "c" direction parallel or perpendicular to the needle symmetry axis.The magnetic anisotropies were studied in details near the critical temperatures using a SQUID magnetometer.

Nuclear spins are a natural choice for various applications requiring long relaxation times, due to their highly localized wave-function which causes a small interaction with the environment. Examples for such applications are vast, among them are bio-sensing using NMR, different kinds of metrology and building blocks for quantum computers. Still, polarization of nuclear spins poses a challenge on every application that involves manipulation of nuclear spin. A method of polarization of single nuclear spins in diamond was suggested in ‎[1] and demonstrated with nuclear spins of 15N, 14N and 13C ‎[1, 2] . The method, applicable at room temperature, is based on the transfer of the polarization of electronic spins of NV- color centers to the nuclear spin at the excited-state level anti-crossing (ESLAC) of the center.

The Standard Model (SM) is the current model of the fundamental particles and their interactions. However, it has to be extended in order to include gravity, dark matter, unify all forces and be extendable to higher energies. Long lived charged particles are allowed by many models of physics beyond the SM. In general, different models have different characteristics.
