    "abstract": "We demonstrate ultrashort (6 ps), multi-Megagauss (27 MG) magnetic pulses\ngenerated upon interaction of an intense laser pulse (10^{16} Wcm^-2, 100 fs)\nwith a solid target. The temporal evolution of these giant fields generated\nnear the high density critical layer is obtained with the highest resolution\nreported so far. Particle-in-cell simulations and phenomenological modeling is\nused to explain the results. The first direct observations of anomalously rapid\ndamping of plasma shielding currents produced in response to the hot electron\ncurrents penetrating the bulk plasma are presented.",
