The pressure partly cancelled the stress causing the increase of T_N. It was observed that the pressure of 1.7±0.2kbar decreased T_N by 3.7±1.0K. From this result it was estimated that in the stressed crystal, labeled "S-(111)-fixed", previously examined, the stress of about 2.5kbar perpendicular to the glued plane caused the increase of T_N by 5K. Pressure dependences of hyperfine field H_ and e^2qQ/2 at 77K were also obtained.}, pages = {29--36}, title = {Calibration of Uniaxial Stress in the KFeF_3 Crystal Used in the Previous Mossbauer Measurement}, volume = {30}, year = {1979} }
