From the Paper:

"Though there are no live forms, yet there is a meteorite present on Earth which had come down some 13,000 years ago in the Antarctic which is raising a lot of questions. This contains a magnetic compound called magnetite or Fe3O4 and that compound is found easily on earth. It is also used in many products like video and audio tapes which are regularly used in most houses. At the same time, there are only very few bacteria on earth which can produce magnetite in the crystalline form as they are able to assemble magnetite structures which are chemically pure and free from any defects. This type of magnetite crystals were found in the Allan Hills meteorite and that is a 4 billion year old rock which had come down from Mars as described earlier. The crystals of magnetite were present deep inside the rock. There is a belief in the scientists that these crystals had traveled all the way from Mars and were not produced on Earth through contamination by bacteria from the Earth after its arrival. (Life on Mars? The Allan Hills meteorite from Mars is peppered with tiny magnetic crystals that on our planet are made only by bacteria) "
