At a temperature far above the superconducting transition Tc ~ 2. 5 K, we reveal a tri-directional charge order with a 2a0 period that breaks the translation symmetry of the lattice.

Through magnetoresistance and current vs. phase measurements, we observed magnetic field sweeping direction dependent magnetoresistance, and an anisotropic interference pattern with a Fraunhofer pattern for in-plane magnetic field, but a suppression of critical current for out-of-plane magnetic field.
