Resumen:
We present the magnetic susceptibility of a new frustrated square lattice system, Pb2VO(PO4)2; and compare it with that measured on our new samples of Li2VOSiO4 and Li2VOGeO4; the only known examples of such magnetic lattice.The analysis of the data using high-temperature series expansion gives a ferromagnetic nearest-neighbor exchange J1 ~ 6 K and an antiferromagnetic next-nearest-neighbor exchange J2 ~ 9.8 K for Pb2VO(PO4)2:
