      abstract     = {Utilizing a combination of the in situ magneto-optical Kerr
                      effect and scanning tunneling microscopy and spectroscopy
                      measurements, we show that the (100) surface of the B2 bulk
                      paramagnetic CoAl is an excellent representation of a
                      two-dimensional ferromagnet. The order-parameter critical
                      exponent beta=0.22 +/- 0.02 is determined, which is the
                      universal signature of a finite-size two-dimensional XY
                      behavior. The Curie temperature is found to be T-c=90 K. The
                      magnetism can be explained by the appearance of Co antisite
                      atoms at the surface.},
