We exploit the magnetic flux rotation effect under tilted fields, and its associated magnetization peak, to study the temperature induced crossover from a 2D to 3D behavior in La1.85Sr0.15CuO4. Measurements of the peak field versus temperature show a pronounced anomaly around the theoretical 2D-3D crossover temperature (∼12 K). Analysis of the data on both sides of this anomaly shows two distinct regimes corresponding to a 2D and 3D behavior.
