  "abstract": "The magnetoresistance components $\\rho_{xx}$ and $\\rho_{xy}$ were measured in two p-Si/SiGe/Si quantum wells that have an anisotropic g-factor in a tilted magnetic field as a function of temperature, field and tilt angle. Activation energy measurements demonstrate the existence of a ferromagnetic-paramagnetic (F-P) transition for a sample with a hole density of $p$=2$\\times10^{11}$\\,cm$^{-2}$. This transition is due to crossing of the 0$\\uparrow$ and 1$\\downarrow$ Landau levels. However, in another sample, with $p$=7.2$\\times10^{10}$\\,cm$^{-2}$, the 0$\\uparrow$ and 1$\\downarrow$ Landau levels coincide for angles $\\Theta$=0-70$^{\\text{o}}$. Only for $\\Theta$ > 70$^{\\text{o}}$ do the levels start to diverge which, in turn, results in the energy gap opening.",
