A complicated electronic structure change around the quantum critical point (QCP) was observed. The electronic structure change across P3 could be attributed to the change of magnetic structure from antiferromagnetic to paramagnetic. The spin and field dependencies diminished across P 3 and finally disappeared above P3. The pressures at low temperatures were determined by the resistivity of manganin wire which was calibrated against the superconducting transition of Tin.
