This paper discusses the development of a new design for spin-exchange-pumped NMR gyros aimed at significantly reducing systematic errors inherent in previous designs. The primary objective is to utilize spin-exchange collisions to drive magnetic resonance in a rotating reference frame about a bias magnetic field, thereby achieving purely transverse polarization. This method is hypothesized to minimize sensitivity to both spin-exchange field shifts and quadrupole interactions. Preliminary studies reveal a novel form of spin-exchange broadening, which can be effectively compensated, thus enabling the system to attain line widths limited by T1 relaxation times. The findings suggest promising advancements in creating a compact yet highly sensitive NMR gyro, with reduced bias instability and enhanced performance in small-scale applications. These initial experiments illustrate the potential for further development of low-noise, stable NMR gyro sensors, thereby contributing to the field of precision measurement technology.
